f IMPROVEMENT IN HOSE-PIPE NOZZLES.

Specification forming part of Letters Patent No. 155,580, dated October 6, 1874; application filed March 25, 1874.

To all whom it may concern:

Be it known that I, ALBERT HALLOWELL, of Lowell, in the .county of Middlesex and Commonwealth of Massachusetts, have invented certain Improvements in Nozzles for Hose-Pipes, of which the following is a speciiication:

My invention has reference to that class of nozzles which produce a spray, as well as a central stream; and consists in an improved shut-eiffor the central stream, and an improved spray-producing device, and also in so This nozzle consists, substantially, of two concentric cylinders, each made in sections for convenience sake, the inner one conveying the central stream, andthe space between the two cylinders being used to supply the spray-oritice, hereinafter described. i

The outer cylinder is attached to the hosepipe by means ofthe screw-thread atA on 'the half globe B. A valve, O, in shape like the frustum of a cone, is concentric with said half-globe, and attached to the top of it by means of two or more supports at equal dis-` tances from each other, one `of which supports is shown at D. The parts B, G, and D are cast in one piece. To the half-'globe B is screwed and soldered the hollow cylinder E.l A sleeve, F, is attached, by two or more supports, G, arranged at equal distances from each other, to the cylinder E, near the top of said cylinder, and concentric with it. Around the cylinder E, and fitting it closely, is the lower end of the case or cylinder H. Another sleeve,rK, is supported by the supports I, of which there are two or more, attached to the case H. The sleeveK surrounds, the sleeve F, and the outer surface of F and the inner surface of K' have corresponding male and female screw-threads, respectively, so that by turning the case H it (H) rises or falls on the cylinder E, and moves the valve O nearer to or farther from the lower end of the pipe L, which lower end of said pipe L is ground out conically to lit said valve C. The pipe L runs up through the sleeve F, which it lits, and screws into an annular flange at the top of the sleeve K, and projects slightly above said liange. Onto the top of the pipe L screws the pipe M. A shoulder on the pipe L, below the flange on the sleeve K, and a similar shoulder on the pipe M, above said flange, keep the central pipe L M in place relatively to the case H. Around the lower end of the pipe L is an external flange, which prevents the sleeve F from being wholly taken out of the sleeve K when said pipe L is in place, so that the sleeve F must be put over the pipeL before the cylinder E and the half-globe B are soldered together. Before the pipe M is attached to the pipe L,.as above set forth, the spray-ring N is screwed over the top of the case H, and the lower end of said ring covered with another ring, O, which latter is made fast to the top of the case H. The ring 0 has a suitable packing in an inside annular groove. The ring N flares outward at its upper end, like the mouth of a bell, and, when unscrewed as far as possible, touches the V-shaped annular ridge P on the pipe M all the way' around. To insure lightness, this ridge I is here made hollow, and a continuous smooth inner surface of the pipe M is secured by soldering in the tube Q. The upper end of the pipe M is many-sided, like a nut, that it maybe turned by a wrench. Whe-n the various parts of the nozzle are thus put together, it will be seen that no part can be separated from the nozzle without first unscrewing the pipe M. A packing of leather or other suitable material is introduced into an annular groove at S in the case H to prevent leakage between said case and the cylinder E. The ring N and the case H are fluted, as shown, in order that they may be more firmly grasped and readily turned.

It' water be forced upward into the bottom 0f the nozzle, said water will rise between the pipe L M and the outer case H, and be forced outward and upward, in the form of' a hollow cone, between the ring N and the ridge P. By unscrewing or screwing upward the case H, and thereby lifting the pipe L from the valve C, the water is allowed to run through the pipe L M, producing a central stream.

It will be seen that the central stream and the hollow' conical or spray stream may be used separately or together, as they are entirely independent of each other, and that by closing both the valve C L and the spray device N P the stream is entirely shut oli'.

By the use of the spray device a screen is interposed between the hoseman and the llire, while he is enabled to throw a stream on the fire. The spray is also useful in driving smoke out of narrow passages and rooms, which is ae- .".omplished bycarrying the pipe alongthrough them, the spray tting the said passages and 4. The combination of the valves N P and CVL, constructed and arranged so that they may be used separately or in connection with each other, as and for the purpose described.
